CONVERTIBLE BED AND TABLE LAMP Filed April 23. 193 1 INVENTOR gEY'WJZTORNEY Patented Dec. 27, 1932 UNITED STATES LOUIS CRANE, F BRONX,NEW YORK CONVERTIBLE BED AND TABLE LAMP Application filed April 23,1931. Serial No. 532,216

This invention relates to lighting fixtures in general, and particularlyto convertible lamps.

The main objects of my invention are to provide an inerpensive device ofthis kind, which may be employed as either desk lamp or bed lamp, andwhich is so constructed as to permit exchange or replacement of partswithout the employment of tools, and which possesses provisions fordirecting light wherever desired, for increasing or reducing the cone oflight emanating from the lamp and for entirely shielding the lightwithout switching off the current.

The foregoing and still further objects will become more readilyapparent as the description of my device progresses, in connection withthe accompanying drawing, forming part of my disclosure, but notintended to limit my invention to the actual showing, and

in which:

Fig. 1 is a front elevation of my device in one of its preferredembodiments, in the position when used as a desk lamp, portions of 5which are shown broken ofi.

Fig. 2 is a side elevation thereof.

Fig. 3 is a cross sectional view through the lamp taken on lines 33 ofFig. 1.

Fig. 4 is a similar cross sectional View through my device, used as abed lamp.

Fig. 5 is an enlarged detail cross sectional view, illustrating thetypical manner of connecting the lamp parts together.

Referring now to the figures, numeral 10 denotes a one piece wiresupport composed of two loops 11, adapted to engage the structure of thelamp, from which the wire continues in the form of two parallel legs,curved ends diverted from the loops as shown at 12 are swung back insemi-loops 13, from which the wire extends in a slight curve 1% to thecross member connecting the legs.

The body of the lamp comprises a cylindri- AK cal member 15 providedwith an opening 16. The inner surface of member 15 is preferably highlypolished or coated so as to serve as a reflector. lVithin the cylinderis op-eratively mounted a shutter 17, which is curved in conformity withthe inner curvature of the cylinder and which extends in width beyondtheside edges of opening 16 and is provided with a stop handle 18 foroperating it and for limiting its movement within the cylinder betweenone horizontal edge of the opening and the other. I

Adapted to extend from the ends of the cylindrical body 15 are twohollow, draw-n members 19 and 20, identical in form, dimensions andconstruction. Their engaging ends are provided with grooves 21 designedfor receiving the looped ends 11 of the lamp support. Next to thegrooves are provided annular enlargements 22 serving, together withloops 11 and the edges of cylinder 15, as limitmg means for end members19 and 20 for preventing their inward movement beyond a desired limit.

Extending inwardly from the grooves of the end members are cylinderengaging portions 23, intended to be held in the cylinder by friction.Their edges 24 are bent inwardly so as to provide annular recesses withthe cylinder, with which register the crimped edges 25 of shutter 17.These recesses form guide grooves and facilitate, together with thecrimped edges of the shutter, the latters smooth movement within thecylinder while at the same time exerting sufficient friction between thethree lamp members, for keeping the shutter at any adjusted position.

Both end members 19 and 20 are interchangeable, although the lattermember is designed for accommodating a light bulb. The extreme outer endportion of member 20 is perforated, for receiving the nipple of lampsocket, held in place by bushing 26. End member 20 is further providedwith means for accommodating some sort of operating mechanism, wherebythe switch within the lamp socket may be actuated. In Fig. 1, I haveillustrated a turn button 27 projecting through the body of member 20,it is obvious however that a chain or press button may be readilysubstituted.

As the drawing plainly indicates, the entire lamp fixture may be rotatedeither wholly or in part within loops 11 of the wire frame. The endmembers may be switched to either end. By rotating the cylinder and Wmby adjusting the shutter the angle of light 1 355 ingly suspending saidfixture by its end membed lamp.

emanating from the device may be altered in any desired manner asindicated by broken lines in Figs. 3 and 4. The support of the fixturepresents its use in the form of a table or desk lamp or as a bed lamp.The bulb holding end member may be entirely removed and usedindependently of the rest of the fixture.

All the above advantages are readily apparent. Nevertheless, myinvention is capa- H ble of changes and improvements which may becomenecessary in the course of manufacture, and be it understood thereforethat I shall have the right to incorporate such improvements within thebroad scope of my invention, as evidenced ,from the annexed claim. I

A In a device of the class described, a lamp fixture comprising afixture body and a fixture support, the former composed'of acylindricalcentre portion provided with an opening, a" shutter operatively. mountedwithin that portion and behind said opening and adapted to slideacrossthe latter and having 7! limiting means for defining itsoperation, in-

terchangeable endv members associated and in frictional engagement withsaid center portion, means provided with said end members for formingguides for said shutter,

other means provided with said end members for accommodating andengaging said fixture support and for limiting their inward movementrelative to said centre portion, said fixture support having provisionsfor revolvbers and being so formed as to facilitate positioning of thefixture either upon a platform or table for use as desk lamp, or itssuspension from a bed end or the like-for use as Signed at New York, inthe county and State of New York, this 30th day of March,
